Application filed March 26, 1909. Serial No. 485,907.

To all whom it may concern:

Be it known that I, ANDREW S. STEEN, a citizen of the United States,residing at Adams, in the county of Walsh, State of North Dakota, haveinvented certain new and useful Improvements in Wrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in wrenches, more particularly toimplements of this character known as combined ratchet and nut wrenches,and has for one of its objects to improve the construction and increasethe efliciency and utility of devices of this character.

lVith this and other objects in view, the invention consists in certainnovel features of construction as hereafter shown and described and thenspecifically pointed out in the claims, and in the drawings illustrativeof the preferred embodiment of the invention, Figure 1 is a view fromone side of the improved implement arranged as a nut wrench. Fig. 2 is afront view,partly in section, of the same. Fig. 3 is a bottom plan viewof the wrench head end of the implement with the nut engaging memberdetached. Figs. at and 5 are perspective views of two of the socketsemployed to adapt the implement to nuts of various sizes. Fig. 6 is aperspective view of the socket employed to receive a bit or drill. Fig.7 is a view of a supplemental wrench element adapted 'to be employed inconnection with the implement. Fig. 8 is a plan view of the nut engagingmember, detached. Fig. 9 is a side elevatlon of the implement arrangedas a ratchet drill.

The improved implement comprises a s'tock 10 flaring outwardly at oneend as shown at 11 and provided with a circular cavity or seat 12 in itsenlarged end and with a plurality of recesses 13 extending into theenlarged portion 11 and leading at the lower ends into the seat 12.Formed within the stock 10 and leading from the seat 12 is alongitudinal socket 14.

Fitting within the socket 14 is a stud 15, and formed upon the stud 15or integral therewith is a ratchet disk 16, the ratchet fitting withinthe seat 12 of the stock. Extending from the outer face of the ratchetis a socket member 17 in which the nut or drill-engaging devices aresupported, as hereafter explained.

Mounted to swing at 18 in each of the recesses 13 is a pawl 19, thepawls engaging at one end in the teeth of the ratchet 16 and eachyieldably supported at its opposite end by a spring 20, the springs thusoperating to maintain the pawls yieldingly in engagement with theratchet, as shown.

The stud 15 is provided with an annular channel 21 in which a pin 22 isengaged, the pin passing through the flaring portion 11 of the stock, asshown. By this means the stud 15 and its attached ratchet disk andsocket member 17 are firmly coupled to the stock while at the same timefree to rotate therein subject 'to the control of the pawls. The socket17 is designed to receive sockets for supporting various sizes of drillsor similar tools.

In Fig. 41 is shown a head 23 ada ted to be supported within the socket17, an large enough to receive a relatively large nut, while in Fig. 5is shown a smaller head 24: adapted to fit within the head 23, and toreceive a smaller size nut, and it is obvious that any required numberof these telescoping heads may be employed, and thus adapt theinstrument to a number of different sizes of nuts. The head 23 isprovided with a friction spring 25 adapted to engage against the innerface of the socket 17 and thus support the head therein, while the head24: is provided with a similar spring 26 adapted to engage by frictionagainst the inner face of the head 23, the springs beingof sufficientstrength to maintain the heads in position against accidentaldisplacement.

If a drill or similar tool is to be employed the form of head shown inFig. 6 will be employed consisting of a block 27 having a drillreceiving socket 28. This device is provided with a spring 29 similar tothe springs 2526, and for the same purpose. By this means it will beobvious that a simply constructed ratchet wrench head is produced.

The end of the stock 10 opposite to the flaring portion 11 is providedwith spaced ears 30-31, and between these cars the re duced terminal 32of an arm 33 is inserted and secured swingingly in position therein by apin 34. By this means the arm is free to swing laterally of the stock.The oint between the parts 1033 is so arranged that when the member 33is arranged at right angles to the member 10 as shown in Fig. 9, the armwill be prevented from moving beyond a right angled position by theconstruction of the joint as will be obvious. \Vhen the arm 33 is thusarranged at right angles to the member 10, it will be obvious that astrong leverage may be obtained. This is an important feature of theinvention and materially increases the efiiciency and advantage withoutmaterial increase of expense or weight.

In Fig. 9 is shown the means for arranging an attachment whentransforming the improvement into a ratchet drill, this attachmentconsisting in a body 35 having a right angled recess at one end wherebytwo arms t7l8 are produced, the arm 4:7 having its inner face curved tobear around the curved end of the arm 32 and the arm 18 having a flatinner face adapted to bear upon the side member 33. Vhen the parts arethus arranged the arm 41-8 is firmly secured by a clamp screw 38 tappedinto the arm 33. The inner end of the body 35 is provided with cavities,one of which is shown at 39, to receive the projecting ends of the ears30--31. The arm 47 partly enwraps the curved end of the member 32 and isthus firmly supported in position by one single clamp bolt 38, as willbe obvious. The body 35 is provided with a threaded bore in its outerend, and fitting in this bore is a feed screw 40 having a conical head41 and the usual rotating pins 42. By this simple means it will beobvious that an efficient ratchet drill is produced, which may bequickly and easily transformed from the nut wrench previously described.

The free end of the arm 33 is reduced as shown at 4-2, and engaging thisreduced portion are the spaced ears 4:344t of a wrench 45, the wrenchbeing swingingly coupled to the arm by a pin 46. The member 46 ispreferably in the form of a threaded pin so that it may be readilydetached to enable wrenches having various forms of jaws to be coupledto the member 33. To this end a wrench having alligator jaws 36 is showncoupled to the member 83, while in Fig. 7 is shown a wrench stock 47having an ordinary nut engaging wrench head 48, the

stock 47 having spaced ears 4950 corresponding to the ears 4H3 of thestock 45, and adapted to be coupled by the pin 46 to the reducedterminal 42 of the member 33.

The improved device is simple in construction, can be inexpensivelymanufac tured, and in various sizes, and of any suitable material, butwill preferably be of tool steel or similar material, so that it willwithstand the severe strains to which implements of this character aregenerally subjected.

Nhat is claimed, is 2- 1. A wrench comprising a stock, a nut engagingdevice at one end of said stock, an arm mounted to swing from theopposite end of said stock, said arm adapted to be located at rightangles to said stock, a supporting body having a right angled recess atone end bearing over the jointed ends of said stock and arm when thesame are in right angular position, means for securing said body to saidarm, and a feed screw operating in said body.

2. A wrench comprising a stock, a ratchet head at one end of said stock,an arm mounted to swing from the opposite end of said stock, said armadapted to be located at right angles to said stock, a supporting bodyhaving a right angled recess at one end bearing over the jointed ends ofsaid stock and arm when the same are in right angular po sition, meansfor securing said body to said arm, and a feed screw operating in saidbody.

3. A wrench comprising a stock formed in two parts swingingly united,means for limiting the movement of the stock parts in one direction, awrench head at one end of one of said stock members, a supporting bodyhaving a right angle recess at one end bearing over the jointed ends ofsaid stock members when the same are in right angular position, meansfor securing said body to said stock members, and a feed screw operatingin said body.

In testimony whereof, I affix my signa ture, in presence of twowitnesses.
